Enterprise-Grade RAG Chatbots: LangChain, AWS Bedrock and Vector Search


Stop using generic AI that hallucinates. As a Backend Engineer with experience in mission-critical banking systems at NTT DATA, I build secure, scalable, and high-performance Retrieval-Augmented Generation (RAG) solutions that actually understand your proprietary data.


Why trust me?


I do not build simple wrappers. I design robust architectures. My background in production troubleshooting and cloud infrastructure (AWS, OpenShift) ensures your AI is reliable, private, and cost-efficient.


What I Offer:

  • Custom RAG Pipeline: LangChain integration with AWS Bedrock (Claude 3.5), OpenAI, or DeepSeek.
  • Advanced Vector Search: Implementation of pgvector, Pinecone, or ChromaDB.
  • Cloud-Native Backend: Scalable API using FastAPI/Python or Spring Boot/Java.
  • Data Intelligence: Smart document processing (PDF, Web, SQL) to minimize hallucinations.
  • Production Ready: Clean code, JWT Authentication, and rigorous testing.

Tech Stack: LangChain, AWS (Lambda, Bedrock, S3), Docker, PostgreSQL, Redis.
